Reflow Oven

Plans

Arc and Redbeard are planning on producing a tutorial for an AVR based reflow oven. The goal of the project is to be an updated version of the sparkfun reflow oven with a better graphical display and improved user input system.

Goals

• Use AVR
• Provide visualization of temperature graph
• Produce board kit
• Be cost equivalent (or cheaper) than sparkfun
• Be programmable via keypad or serial port
• Provide real time output via serial
• All through hole (otherwise you're in chicken vs egg mode)

Parts List

• SPST Relay (at least 30 amps)
• AVR (At least ATMega168, possibly ATMega328
• Thermocouple
• LCD Display
• Keypad
• Fuse Holder?
• Thermocouple Amplifier

Upgrades

• Line inside of oven with Reflect-a-gold - Manufacturer's Link (Will improve cooling ramp down times)

Links

• Reflow Kit @ Sparkfun (the project to beat!)
• LCD Screen @ Sparkfun
• SPST 30A Relay @ Sparkfun
